2018 International Symposium on Ultra-High-Energy Cosmic Rays UHECR 2018

Second circular

Dear Colleagues,

We would like to remind you of the international symposium on Ultra High Energy Cosmic Rays, “UHECR2018”, which will be held in Paris from 8 to 12 October 2018. The symposium will begin Monday et 1pm and end Friday at 1pm. In addition, a small workshop on future challenges of UHECR physics is planned for Friday afternoon. The symposium website is https://indico.in2p3.fr/event/17063/

Review talks on the latest IceCube, IceTop, Auger, and TA results will be presented, and we will hear reports from different inter-collaboration working groups on spectrum, composition, anisotropy, at the highest energy and in the transition region, and as well as on hadronic interactions in extensive air showers. Moreover,  working groups on searches for neutral primary particles, on searches for neutrino-UHECR cross-correlations, and on the Auger@TA  project will report on their ongoing activities.

Invited review talks will be also given on the following subjects: 

  • Acceleration to the highest energies
  • Source scenarios including propagation
  • Magnetic fields
  • Diffuse gamma-ray background from Fermi-LAT
  • Physics of the transition from Galactic to extragalactic CRs
  • Hadronic interactions related to EAS interpretation
  • Gravitational waves related to neutron star merger physics
  • Multi-messenger connection of UHECR, neutrinos, gamma rays


The web page will be regularly updated with respect to the invited talks.
The symposium is  open to oral or poster contributions. Abstract submission starts on  June  18th. Please submit your abstracts via https://indico.in2p3.fr/event/17063/abstracts/ before July 25th. We will notify acceptance of abstracts to authors by the end of July.

The registration fee is 320 €. It includes: admission to all scientific sessions, coffee/tea breaks, welcome cocktail on Monday the 8th of October, and the social event, including a guided tour at the “Musée d’Orsay” and the conference dinner at the museum restaurant. It will be held on October 11th. The fee of the social event for each additional guest is 75 euros. Online proceedings edition is also included in the conference fee.

For payment, please follow instructions at https://indico.in2p3.fr/event/17063/registrations/1852/

There are many hotels and restaurants surrounding the campus, but we recommend that you book your hotel as soon as possible because Paris is always busy.

If you have any question, please do not hesitate to contact us via the LOC email uhecr2018@ipno.in2p3.fr.
